Imitative Folles or "barbarous" bronze coins from this series are plentiful and range from extremely crude to nearly official in appearance. RIC footnotes as "irregular" or "semi-barbarous". On p. 224, Appendix to Trier, RIC VII describes and lists a number of "irregular" coins for the purpose of "illustrating the wide range of varieties known".
